FLAT-IRON AND BURNER.

Specification of Letters Patent.

Application filed April 30, 1913. Serial No. 764,586.

Tool} whom it may concern Be it known t at we, BURTON R. LARA- WAY and WILLIAM J .1 HANDLEY, citizens of the United States, and residentsof the city of Jackson, in the county of J ackson and State of ldichigan, have invented a certain new and Improved Flat-Iron and Burner, of which the following, taken in connection with the accompanying drawing, is a specification fully disclosing a complete and operative embodiment of the invention. a

Our invention relates to that type of flat irons which are continuously heated during their use and operation and it especially concerns flat irons ofthe kind in which natural or artificial gas coming direct from the gas mains is utilized as the fuel to heat the iron. In the use of such fuel it is important that complete combustion thereof be had otherwise an offensive odor not unattended with danger will be present throughout the use of the iron. At the same time it is desirable that all the heat units of the fuel burned shall be utilized without waste or loss. It is common in the usual kinds of gas using flat irons to provide for the complete combustion thereof by mixing a portion of air with the gas before it reaches the burner which is located within the iron, lighting this mixture as it passes from the burner and supplying more air which is needed through openings made in the walls of the flat iron body. This is open to objection in that the openings in the walls introduce cold air across the under wall of the iron which is the part heated, cooling it, and such openings also allow the flame of the burning gas to pass therethrough on sidewise movement of the iron during its use.

It is the object and purpose of this invention, primarily, to produce a burner for use in burning natural or artificial gas taken from the gas mains that ordinarily supply houses using gas, in an inclosed space without resort to an auxiliary supply of air, this burner being adapted especially for use within the well of a fiat-iron of the self heating type, and to so construct such burner and adapt it for flat irons that no auxiliary or side openings need be made in the walls of the well to supply air, doing away with such openings and the danger and expensiveness thereof.

It is a further object of the invention to provide an escapement portion in the burner for the passage of the mixed gas and air thcrethrough so designed that the escape of the mixture is regulated to cause an even passage through substantially all of the escapement portion and in such quantity that the flame of the burning mixture is of slight depth so that the burner may be placed in close proximity to the bottom wall of the well. It is also purposed to attach such escapement portion to the body of the burner in such manner that the expansion due to its heating upon burning the fuel will be easily and completely taken care of.

Various other objects and purposes than those specifically enumerated will be evident as understanding is had of the construction outlined in the drawing in which,

Figure l is a vertical section lengthwise of a flat iron equipped with the burner, taken on line (z-a, Fig. 2. Fig. 2 is a trans verse vertical sectlon as taken on line c-c, Fig. 1. Fig. 3 is a view of the burner used looking at it from beneath. Fig. 4 is a fragmentary sectional view, enlarged, of the mounting of the gas escapcmcnt plate in the sides of the burner body. Fig. 5 is a fragmentary elevation of the rear upper part of the flat iron showing the means of securing the top of the body of the iron.

Similar reference numerals refer to similar parts thrmlghout the several views of the drawing. 7

The fiat iron is of the hollow body formation usual in irons of this type and comprises a well member 1 having a bottom wall 2 and side walls 3 together with a back wall 4. forming an inclosure open at the top which is covered by the cover 5, such cover having detachable connection with the well member in the usual way, an integral downward and forwardly angular projection 6 on the cover engaging under a ledge 7 at the front of the well member, and a screw member 8 threaded into a lug 9 positioned on the rear wall of the well being used to hold the cover securely in position on the well. The cover has attached thereto the handle members 10 and 11. The sides 3 of the well extend nearly to the under surface of the cover being cut away to form the exhaust openings at 12 through which the products of combustion pass when the burner is lighted. The burner is attached to and moves with the cover when it is detached from the well. Such attachment is accomplished by the screw 13 threaded into a projection 14; located substantially midway of the length of the burner, and extending upwardly therefrom, and two upwardly extending parts 15 to either side of the part 14 and integrally cast with the body of theburner bear against the under side of the cover- ,On tightening the screw thus firmly securing such body to the cover. The burner body is of a length to extend nearly the full distance betweenthe ends of .the well and 00m prises spaced apartside's 16, a curved integral top 17 which bends down to meet the inwardly bent sides at the front end to inclose such end, and a back end 18, leaving an open under side which is provided with the plate 19 through which the gas escapes for ignition. The structure of this plate and its connection with the body portion of the burner formsan important feature of our invention. .The sides 16 near their lower edges are sawed to make the slots 20 into which the plate 19 is inserted. and slid'forward to close the open side of the burner.v

23 is threaded into the lip 21 passing through plates 22 and 19. The plate is perforated in a plurality of places as shown at 24c, such perforations being of small diameter and very closely spaced throughout the whole length'and breadth of the plate 19. By making the plate of such structure and the burner body of a size in excess of the usual burner bodies, there is provided a reservoir for fuel above the plate holding more'than is immediately needed, whilethe plate by reason of its numerous evenly and uniformly spaced perforations over all of the lower part of the burner serves as a retarding means for the escape of the mixture until the reservoir is filled and then allows it to' escape'uniformly through the perforations.

This is very necessary in order that the working surface of the iron shall be uniformly heated and not be liable to burn out at any part subject to over heating. This retardation of the free escape of the gas keeps the reservoir full and in. a state of uniform pressure, and allows escape only sufficiently to make a flame when lighted of substantially an eighth of an inch in depth, uniformly distributed over the surface of the plate. The burner, accordingly, is positioned low-in the well so that the flame said wall quickly heating it and keeping'it the reservoir formed thereby is shown, at

the gas and air mixturepassed into a space at the "desired temperature with a minimum amount of fuel. 7 in The conduit for carrying the mixed air and gas to'jithe burner and delivering it to (l 25,:consisting of a pipe threaded into the 7 back-end of theburner and extending thence at an angle for a distance, and having at its free end a cap 26 formed approximately as a hollow sphere, the walls of which are pierced. at aplurality of places at 27 for the admission of air and at 28 to receive the gas inlet tube 29. Tube 29 is threaded'into cap 26 directly opposite the pipe25 and inits inner end is providedv with a tip '30 having a small opening therethrough for permit ting the passage of a limited supply of gas. The pipe 25 is of a diameter largely in excess of that merely required'to carry the gas so that when thegas enters .it, a sufiicient.

supply of air is carried along'with it through evenly therein without causing an extra sup ply of the mixture to pass through plate'19 nearest the rear end as would be the case if l restricted as in ordinary burners. The rear wall t is cut away to permit the pipe25 to pass in the notch made as shown.

Inoperation, the tube 29 has a flexible gas tubing attached thereto in the ordinary manner and gas is passed therethrough from any convenient .fixture through the tip 30 into the cap 26, receiving on its passage into the tube 25 an excess of air through openings 27. Entering the burner, the mixture first fills the space therein and spreads evenly over the. plate 19-before passing throughthe apertures at 24. Before turningthe gas on, the cover 5 with the attached burner may be removed from the well mem- 0 her 1 and as the gas begins. to pass through which on burning requires no auxiliarysup- 1Z0 ply of air to complete the combustion, and

the retardation of the flowthrough the plate in connection with the extrasize and capacity of the burner body causes an, even pressure over the entire surface of the plate 25 such that when theinclosed burner space is filled, the combustible mixture flows evenly through the holes at 24 making a uniform flame possible. This is a'very important feature of our invention and one 139 of great practical utility as the flame is kept within the walls of the Well and has no place to pass through as in the case with well members pierced to receive auxiliary air, and no cooling of the bottom wall is had by passage of cold auxiliary air over it, while the mounting of the escapement plate in the burner body is such that all expansion is provided for and the plate always presents a plane even surface all portions of which are an equal distance from the bottom wall 2.

l/Ve have fully described a complete and practically operative embodiment of our invention, in which gas piped directly from the gas mains and mixed with air at ordinary atmospheric pressure is introduced into a burner and evenly taken therefrom without the use of auxiliary attachments of any kind to secure complete combustion.

WVhat we claim as new and desire to secure by Letters Patent is 1. In a flat iron, the combination with a hollow base member having integral base and imperforate side members, of aburner located lengthwise of said base member and positioned above the base wall thereof, said burner comprising a hollow member open on its under side and a plate detachably secured to the hollow member to close said side, a conduit tube entering at an incline at one end of the burner, a cap with air openings secured to such tube and a gas tube entering the cap, the conduit tube having an inside diameter largely in excess of that required to carry the gas, and the burner having inside sectional, area in excess of that of the tube, apertures uniformly located in the plate over its entire surface and of a size to retard the free flow of gas therethrough. whereby a reservoir of gas is formed in the burner and an even pressure given to the gas contained therein to cause its even and uniform discharge through the apertures over the entire surface of the plate.

2. In a flat iron, a well member having a base and imperforate upwardly extending sides, a cover for the well member, a burner located lengthwise of the well member and extending substantially the entire length thereof, said burner comprised of a body member having spaced apart sides, top and ends and a plate secured to the sides opposite the top, said burner having comparatively large cross section whereby there is provided a. reservoir for gas of comparatively large capacity, a conduit tube leading into the burner at one end and located at an incline to the burner but with the axis of the conduit in substantially the same ver tical plane as the axis of the burner, said tube having inner section less than that of the burner, means to introduce gas and air into the tube whereby a mixture with an excess of air. is obtained, apertures in the plate uniformly distributed over the entire surface thereof, said apertures being of small size and serving to retard the free passage of gas whereby there is caused a uniform pressure within the chamber of the burner, said apertures allowing the uniform passage of the gas through all the apertures under the influence of such pressure.

3. In a gas burner, a hollow burner member, a plate forming one side of the burner member, spaced apart sides forming other portions of the burner member, slots cut in said sides of a width greater than the thickness of the plate and of a depth such that the distance between the bottoms there- 7 of is greater than the width of the plate, said plate being seated in said notches, whereby provision is made for the expansion thereof when heated during the operation of the burner, portions cut away from one end of the burner adjacent the slots whereby the plate may be slidably inserted into or removed from the slots, and means for retaining the plate in position when inserted into the slots.

4. In a gas burner, a hollow member having an open side, a plate provided with apertures detachably connected to the hollow member and closing the open side thereof, means provided in the connection of the plate to the member to afford room for the expansion of the plate when heated during the operation of the burner, and a fastening element adapted to secure the plate in position with respect to the said member, said element being passed through the plate and into the wall of the said memher.

In testimony whereof, we have hereunto aflixed our signatures in the presence of two witnesses.
